jenkins - Jenkins 管道中的变量

Question

为了使我的 jenkins 管道定义文件更具可定制性，我尝试使用最多的变量。

当我尝试在 中使用变量时邮箱 或 步骤 指令 Jenkins 抛出这个错误:

java.lang.NoSuchMethodError: No such DSL method '$' found among [archive, bat, build, catchError, checkout, deleteDir, dir, echo, emailext, emailextrecipients, error, fileExists, git, input, isUnix, load, mail, node, parallel, properties, pwd, readFile, readTrusted, retry, sh, sleep, stage, stash, step, svn, timeout, timestamps, tool, unarchive, unstash, waitUntil, withCredentials, withEnv, wrap, writeFile, ws]

这是我的 jenkins pipleline 定义文件:

#!groovy
node {

    //Define job context constants
    def projectName = "JenkinsPipelineTest"
    def notificationEmailRecipients = "aaa@domain.com"
    def notificationEmailSender = "bbb@domain.com"
    currentBuild.result = "SUCCESS"

    //Handle error that can occur in every satge
    try {

            //Some others stage...

            stage 'Finalization'
            step([$class: 'ArtifactArchiver', artifacts: '*.zip, *.tar, *.exe, *.html', excludes: null])
            step([$class: 'Mailer', notifyEveryUnstableBuild: true, recipients: ${notificationEmailRecipients}, sendToIndividuals: false])
    }
    catch (err) {
        //Set built state to error
        currentBuild.result = "FAILURE"

        //Send error notification mail
        mail body: ${err},
        charset: 'UTF-8',
        from: ${notificationEmailSender},
        mimeType: 'text/plain',
        replyTo: ${notificationEmailSender},
        subject: '"${projectName}" meet an error',
        to: ${notificationEmailRecipients}

        throw err
    }
}

这是正常的还是我的定义文件中有错误？

Answer 1

这是我的错!

我混淆了字符串中的变量和变量和 Groovy 代码:

代码:

step([$class: 'Mailer', notifyEveryUnstableBuild: true, recipients: ${notificationEmailRecipients}, sendToIndividuals: false])

必须是:

step([$class: 'Mailer', notifyEveryUnstableBuild: true, recipients: notificationEmailRecipients, sendToIndividuals: false])

这里我一定不能用 ${} 因为我在 Groovy 代码中而不是在字符串中。

第二个错误，邮件正文必须是:

mail body: "Error: ${err}"

并不是:

mail body: ${err}

因为 错误 这是一个 IOException 类实例而不是字符串。

所以最终的代码是:

#!groovy
node {

    //Define job context constants
    def projectName = "JenkinsPipelineTest"
    def notificationEmailRecipients = "aaa@domain.com"
    def notificationEmailSender = "bbb@domain.com"
    currentBuild.result = "SUCCESS"

    //Handle error that can occur in every satge
    try {

            //Some others stage...

            stage 'Finalization'
            step([$class: 'ArtifactArchiver', artifacts: '*.zip, *.tar, *.exe, *.html', excludes: null])
            step([$class: 'Mailer', notifyEveryUnstableBuild: true, recipients: notificationEmailRecipients, sendToIndividuals: false])
    }
    catch (err) {
        //Set built state to error
        currentBuild.result = "FAILURE"

        //Send error notification mail
        mail body: "Error: ${err}",
        charset: 'UTF-8',
        from: notificationEmailSender,
        mimeType: 'text/plain',
        replyTo: notificationEmailSender,
        subject: '${projectName} meet an error',
        to: notificationEmailRecipients

        throw err
    }
}

希望这个答案会有所帮助。
